Initial Check
NOTE: If oil supply to the accessory drive is not required
and the gasket does not have oil passages, this check is
not required. If the accessory drive uses o-rings for seals,
this check is not required.
Prior to installing the accessory drive, identify which
gasket is going to be installed so that, if necessary, the
gasket can be properly oriented.
There are two types of accessory drive gasket:
1 Three round oil supply passages and one elongated oil
supply passage
2 Four round oil supply passages.
It is preferred that, when installing the accessory drive, the
gasket with the four round oil supply passages be used.
The gasket can be installed in any orientation.
If only the gasket with the one elongated oil supply
passage is available, install the gasket so that the
elongated oil supply passage is not over the oil supply
hole in the gear housing.
Install
CAUTION
Failure to line up the oil supply hole to the accessory
drive properly will result in accessory drive damage.
Install the accessory drive and new gasket.
NOTE: If required, when installing the accessory drive
and gasket, make sure the oil supply hole in the gear
housing is lined up with the holes in the accessory drive
and gasket. The accessory drive is marked for “Top” and
“Bottom”.
Install and tighten the two capscrews securing the
accessory drive to the rear gear housing.
